- Systems and methods are provided for modeling teeth in creating a treatment plan.
- the systems and methods compress data associated with the teeth model to reduce the storage size and transmission time to a treating professional.
- the teeth can be incrementally moved using a plurality of discrete appliances, where each appliance successively moves one or more of the patient's teeth by relatively small amounts.
- a representative jaw 100 includes sixteen teeth, at least some of which are to be moved from an initial tooth arrangement to a final tooth arrangement.
- an arbitrary centerline (CL) is drawn through one of the teeth 102 .
- the teeth may be moved in the orthogonal directions represented by axes 104 , 106 , and 108 (where 104 is the centerline).
- the centerline may be rotated about the axis 108 (root angulation) and 104 (torque) as indicated by arrows 110 and 112 , respectively.
- the tooth may be rotated about the centerline.
- the magnitude of any tooth movement is defined in terms of the maximum linear translation of any point P on a tooth 102 .
- Each point P 1 will undergo a cumulative translation as that tooth is moved in any of the orthogonal or rotational directions defined in FIG. 1 A. That is, while the point will usually follow a non-linear path, there will be a linear distance between any point in the tooth when determined at any two times during the treatment.
- an arbitrary point P 1 may in fact undergo a true side-to-side translation as indicated by arrow d 1 , while a second arbitrary point P 2 may travel along an arcuate path, resulting in a final translation d 2 .
- the maximum permissible movement of a point P 1 in any particular tooth is defined as the maximum linear translation of that point P 1 on the tooth which undergoes the maximum movement for that tooth in any treatment step.
- One tool for a incrementally repositioning the teeth in a patient's jaw is a set of one or more adjustment appliances.
- Suitable appliances include any of the known positioners, retainers, or other removable appliances which are used for finishing and maintaining teeth positions in connection with conventional orthodontic treatment. As described below, a plurality of such appliances can be worn by a patient successively to achieve gradual tooth repositioning.
- a particularly advantageous appliance is the appliance 101 , shown in FIG. 1C, which typically comprises a polymeric shell having a cavity shaped to receive and resiliently reposition teeth from one tooth arrangement to another tooth arrangement. The polymeric shell typically fits over all teeth present in the upper or lower jaw.
- teeth will be repositioned while others will provide a base or anchor region for holding the repositioning appliance in place as it applies the resilient repositioning force against the tooth or teeth to be repositioned.
- many or most of the teeth will be repositioned at some point during the treatment.
- the teeth which are moved can also serve as a base or anchor region for holding the repositioning appliance.
- the gums and the palette also serve as an anchor region in some cases, thus allowing all or nearly all of the teeth to be repositioned simultaneously.
- the polymeric appliance 101 of FIG. 1C is preferably formed from a thin sheet of a suitable elastomeric polymeric, such as Tru-Tain 0.03 in. thermal forming dental material, marketed by Tru-Tain Plastics, Rochester, Minn. 55902.
- a suitable elastomeric polymeric such as Tru-Tain 0.03 in. thermal forming dental material, marketed by Tru-Tain Plastics, Rochester, Minn. 55902.
- no wires or other means are provided for holding the appliance in place over the teeth.
- FIG. 2 shows a process 200 for producing the incremental position adjustment appliances for subsequent use by a patient to reposition the patient's teeth.
- an initial digital data set (IDDS) representing an initial tooth arrangement is obtained (step 202 ).
- the IDDS may be obtained in a variety of ways.
- the patient's teeth may be scanned or imaged using X-rays, three dimensional X-rays, computer-aided tomographic images or data sets, or magnetic resonance images, among others. More details on the contact or non-contact scanners are in commonly-owned and co-pending application Ser. No. 09/169,276, filed Oct. 8, 1998, the content of which is incorporated by reference.
- a plaster cast of the patient's teeth is obtained by well known techniques, such as those described in Graber, Orthodontics: Principle and Practice , Second Edition, Saunders, Philadelphia, 1969, pp. 401-415.
- the casting is digitally scanned by a scanner, such as a non-contact type laser or destructive scanner or a contact-type scanner, to produce the IDDS.
- the data set produced by the scanner may be presented in any of a variety of digital formats to ensure compatibility with the software used to manipulate images represented by the data.
- a user may wish to gather data about hidden features, such as the roots of the patient's teeth and the patient's jaw bones.
- This information is used to build a more complete model of the patient's dentition and to show with more accuracy and precision how the teeth will respond to treatment.
- information about the roots allows modeling of all tooth surfaces, instead of just the crowns, which in turn allows simulation of the relationships between the crowns and the roots as they move during treatment.
- Information about the patient's jaws and gums also enables a more accurate model of tooth movement during treatment.
- an x-ray of the patient's jaw bones can assist in identifying ankylose teeth
- an MRI can provide information about the density of the patient's gum tissue.
- information about the relationship between the patient's teeth and other cranial features allows accurate alignment of the teeth with respect to the rest of the head at each of the treatment steps. Data about these hidden features may be gathered from many sources, including 2D and 3D x-ray systems, CT scanners, and magnetic resonance imaging (MRI) systems. Using this data to introduce visually hidden features to the tooth model is described in more detail below.
- the IDDS is manipulated using a computer having a suitable graphical user interface (GUI) and software appropriate for viewing and modifying the images. More specific aspects of this process will be described in detail below.
- GUI graphical user interface
- Individual tooth and other components may be segmented or isolated in the model to permit their individual repositioning or removal from the digital model. After segmenting or isolating the components, the user will often reposition the tooth in the model by following a prescription or other written specification provided by the treating professional. Alternatively, the user may reposition one or more teeth based on a visual appearance or based on rules and algorithms programmed into the computer. Once the user is satisfied, the final teeth arrangement is incorporated into a final digital data set (FDDS) (step 204 ).
- FDDS final digital data set
- the FDDS is used to generate appliances that move the teeth in a specified sequence.
- the centers of each tooth model may be aligned using a number of methods. One method is a standard arch. Then, the teeth models are rotated until their roots are in the proper vertical position. Next, the teeth models are rotated around their vertical axis into the proper orientation. The teeth models are then observed from the side, and translated vertically into their proper vertical position. Finally, the two arches are placed together, and the teeth models moved slightly to ensure that the upper and lower arches properly mesh together. The meshing of the upper and lower arches together is visualized using a collision detection process to highlight the contacting points of the teeth.
- step 204 final positions for the upper and lower teeth in a masticatory system of a patient are determined by generating a computer representation of the masticatory system.
- An occlusion of the upper and lower teeth is computed from the computer representation; and a functional occlusion is computed based on interactions in the computer representation of the masticatory system.
- the occlusion may be determined by generating a set of ideal models of the teeth.
- Each ideal model in the set of ideal models is an abstract model of idealized teeth placement which is customized to the patient's teeth, as discussed below. After applying the ideal model to the computer representation, and the position of the teeth is optimized to fit the ideal model.
- the ideal model may be specified by one or more arch forms, or may be specified using various features associated with the teeth.
- a plurality of intermediate digital data sets are defined to correspond to incrementally adjusted appliances (step 206 ).
- a set of incremental position adjustment appliances are produced based on the INTDDs and the FDDS (step 208 ).
- FIG. 3 shows one exemplary 3D surface model of the teeth.
- the surface topology of a 3D model of teeth on a jaw can be modeled as a set of polygons of appropriate sizes and shapes joined at their edges.
- the set of polygons defining the 3D object is referred to as the “model” or “mesh” for the 3D object.
- the polygons are triangles.
- a triangle mesh is a piecewise linear surface with triangular faces joined along their edges.
- voxels volume elements
- a marching cubes algorithm is applied to convert the voxels into a mesh, which can undergo a smoothing operation to reduce the jaggedness on the surfaces of the tooth model caused by the marching cubes conversion.
- One smoothing operation moves individual triangle vertices to positions representing the averages of connected neighborhood vertices to reduce the angles between triangles in the mesh.
- the triangles in FIG. 3 form a connected graph.
- two nodes in a graph are connected if there is a sequence of edges that forms a path from one node to the other (ignoring the direction of the edges).
- connectivity is an equivalence relation on a graph: if triangle A is connected to triangle B and triangle B is connected to triangle C, then triangle A is connected to triangle C.
- a set of connected nodes is then called a patch.
- a graph is fully connected if it consists of a single patch. The processes discussed below keep the triangles connected.
- models of the patient's individual teeth can be derived.
- individual teeth and other components are “cut” using a cutting tool to permit individual repositioning or removal of teeth in or from the digital data.
- a prescription or other written specification provided by a treating professional is followed to reposition the teeth.
- the teeth may be repositioned based on the visual appearance or based on rules and algorithms programmed into the computer.
- FIG. 4 shows an embodiment of a process for communicating the 3D model of the teeth to the treating professional. Since realistic models have a large volume of data, the storage and transmission of the models can be expensive and time consuming. To reduce transmission problems arising from the large size of the 3D model, the system compresses the data associated with the model. In the embodiment of FIG. 4, the compression is done by modeling the teeth meshes as a curve network (step 220 ). Next, the curve network is transmitted to the treating professional (step 222 ). The curve network can be sent over a local area network (LAN) or a wide area network (WAN) such as the Internet. At the receiving end, once the curve network is received, the 3D model is reconstructed from the curve network for the treating professional to analyze (step 224 ).
- LAN local area network
- WAN wide area network
- step 220 The curve network generation of step 220 is shown in more detail in FIG. 5 .
- the process of FIG. 5 obtains one or more sample points from the meshes of a tooth (step 230 ).
- the process computes tangent values for the sample points (step 232 ).
- the sample points are converted into u, v-space (step 234 ).
- a grid or curve network is generated that satisfies the points in u, v-space (step 236 ). This is done by surface fitting the curve network to the original data.
- data points are separated into groups.
- a U-curve with a U-knot vector is interpolated through each separate group.
- one or more V-curves are generated by moving along each of the U-curves for a given knot value.
- the V-curve is formed by interpolating through these data points.
- the V-curves intersect the U-curves at points of constant u.
- a new set of U-curves that are constant in v is obtained by connecting points of constant v along the V-curves.
- a network of curves and its relationship to the original data points can then be generated.
- FIG. 6A shows a flowchart for a process to create an M ⁇ N curve network associated with a tooth.
- the process determines M, the number of slices corresponding to meridian lines crossing the tooth (step 240 ).
- the process calculates tangent values for a plurality of planes intersecting with the tooth to define a curve associated with one side of a slice (step 242 ).
- One or more sample points and sample tangent values for the sample points are selected (step 244 ) and the length of the curve is computed (step 246 ).
- the process of FIG. 6 divides the length of the curve the N and generates points associated with the M ⁇ N curve network (step 248 ).
- the curve network is a network of M meridian lines and N parallel lines. For each meridian line, a plane is selected to contain the meridian line. A series of points representing an intersection between the plane and the triangle mesh modeling a tooth is determined. The series of points represent a curve whose length is then determined. The length of the meridian is divided by N. If M is 20 and N is 20, a 20 ⁇ 20 grid of points is generated, each point being represented in 3-D. In this manner, M ⁇ N 3D points can be transmitted in place of the voluminous mesh representation of the teeth. To further reduce the size of the file, the coordinates of each point are stored using integer values rather than floating point values.
- FIG. 6B a second process 300 for fitting a curve network to a tooth is shown in FIG. 6B, and exemplary diagrams illustrating the operation of the process 300 on a tooth model are shown in FIGS. 6C and 6D.
- a tooth basis is created (step 301 ).
- the tooth basis has its origin inside the tooth such as in the middle of the tooth.
- the z-axis points towards an occlusion surface
- the y-axis points to a labial tooth surface
- the x-axis points to a mesial direction.
- the process 300 selects the number of meridians M. M can range between 20-40. Also, the process 300 selects the number of points on each meridian N. N is typically ranges between 2/3M to M.
- a set of M half planes 0, . . . , (M ⁇ 1) is created: each half plane goes through the tooth z-axis, and the plane i forms an angle (2*PI/M)*i with the tooth x-axis (step 302 ). Exemplary half planes are shown in FIG. 6 C.
- an intersection with the tooth mesh surface is determined (step 304 .
- This intersection is a polyline that goes from the lower intersection of z-axis with the tooth surface to their upper intersection (points A and B). This line is called a meridian line.
- the data is saved and sent to a treating professional.
- the grid of M by N points is used to generate a surface that closely resembles a tooth.
- 20 is used in one embodiment, other values for M or N can be 30 or 40.
- a Hermit spline F is specified that maps a rectangle [0, M]*[0, N] in (u, v) parameter plane into 3D space.
- the Hermit spline F is a smooth continued function on the [0, M]*[0, N] rectangle.
- the spline is a bicubic 3D function.
- the restriction of F onto [m, m+1]*[n, n+1] square is denoted by f (omitting the indices (m, n) that should signify that functions f are different on different squares).
- 3D values F, two derivatives dF/du, dF/dv, and the second mixed derivative d2F/dudv in each nod point (m, n) are specified.
- 3D values f, two derivatives df/du, df/dv, and the second mixed derivative d2f/dudv are generated for the four square comers (m, n), (m+1, n), (m, n+1), (m+1, n+1).
- a unique 3D bicubic function is completely determined by those values. The bicubic functions on the next squares are smoothly connected because the values and derivatives are the same on the common side.
- the 3D values F, two derivatives dF/du, dF/dv, and the second mixed derivative d2F/dudv in the nod points (m, n) are specified as follows:
- FIG. 7 shows an original high resolution model 250 of a group of lower teeth and various compressed models of the high resolution model of the teeth.
- the original high resolution model requires 2.373 megabytes of data.
- a 20 ⁇ 20 model 252 requires 93 kilobytes
- a 30 ⁇ 30 model 254 requires 135 kilobytes
- a 40 ⁇ 40 model 256 requires 193 kilobytes.
- the reduction in the size of the file reduces the storage as well as transmission requirements while maintaining good quality.
- At least one orthodontist had noted that the 30 ⁇ 30 model is, for his application, as good as the original high resolution model 250 in developing a treatment plan.
- decimation operations can be applied to the mesh of teeth to eliminate data points, which improves processing speed. After the smoothing and decimation operation have been performed, an error value is calculated based on the differences between the resulting mesh and the original mesh or the original data, and the error is compared to an acceptable threshold value. The smoothing and decimation operations are applied to the mesh once again if the error does not exceed the acceptable value. The last set of mesh data that satisfies the threshold is stored as the tooth model.
- the mesh model can be simplified by removing unwanted or unnecessary sections of the model to increase data processing speed and enhance the visual display.
- Unnecessary sections include those not needed for creation of the tooth repositioning appliance. The removal of these unwanted sections reduces the complexity and size of the digital data set, thus accelerating manipulations of the data set and other operations.
- the software After the user instructs the software to erase unwanted sections, all triangles within the box set by the user are removed and the border triangles are modified to leave a smooth, linear border.
- the software deletes all of the triangles within the box and clips all triangles which cross the border of the box. This requires generating new vertices on the border of the box.
- the holes created in the model at the faces of the box are retriangulated and closed using the newly created vertices.
- the computer automatically simplifies the digital model by performing the user-oriented functions described above.
- the computer applies a knowledge of orthodontic relevance to determine which portions of the digital model are unnecessary for image manipulation.
- data associated with the 3D model includes features can be compressed based on observed characteristics of the tooth surfaces.
- the system can use the curvature of a particular molar between the tips of the cusps and the gumline to predict the shape of the roots for that molar.
- Models of typical root and crown shapes also can be used to provide predict the shape of the tooth. The information used to arrive at the predicted shapes can be used in lieu of the original data, thus effecting data compression.
- MAP Maximum a posteriori
- Prior images to model pixel values corresponding to distinct object types (classes) as independent random variables with normal (Gaussian) distributions whose parameters (mean and variance) are selected empirically. For each class, a histogram profile is created based on a Gaussian distribution with the specified mean and variance.
- the prior images supply for each pixel and each class the probability that the pixel belongs to the class, a measure which reflects the relative frequency of each class.
- the pixel values in the input image are scaled according to the prior probabilities, then by the distribution function.
- the result is a posterior probability that each pixel belongs to each class.
- the Maximum a posteriori (MAP) approach then selects for each pixel the class with the highest posterior probability.
- a treating clinician is able to view a patient's treatment plan and alter or comment on the plan.
- the client viewer application is implemented in a computer program installed locally on a client computer at the clinician's site.
- the viewer program downloads a data file from a remote host, such as a file transfer protocol (FTP) server maintained by the treatment plan designer, which can be accessed either through direct connection or through a computer network, such as the World Wide Web.
- FTP file transfer protocol
- the viewer program uses the downloaded file to present the treatment plan graphically to the clinician.
- the viewer program also can be used by the treatment plan designer at the host site to view images of a patient's teeth.
- 3-D images of various orthodontic views can then be rendered after the compressed data of the teeth has been received.
- an origin point, or “look from” point associated with a camera view is generated.
- a “look at” point or a focus point associated with the camera view is determined.
- the line from LookFromPoint to LookAtPoint defines the direction the camera is shooting at.
- a camera Z vector, or up vector is determined.
- Pseudo code for generating various orthodontic views is shown below.
- the code defines a boundingbox of one mold (2 arches) which is the smallest cube containing the molds geometry.
- Other settings associated with the bounding box include:
- Z_Axis point from lower to upper
- Y_Axis point from inside mouse to front teeth (incisors)
- X_Axis point from center to left.

- the appliances may be fabricated as illustrated in FIG. 8 .
- Common fabrication methods employ a rapid prototyping device 201 such as a stereolithography machine.
- a particularly suitable rapid prototyping machine is Model SLA-250/50 available from 3D System, Valencia, Calif.
- the rapid prototyping machine 201 selectively hardens a liquid or other non-hardened resin into a three-dimensional structure which can be separated from the remaining non-hardened resin, washed, and used either directly as the appliance or indirectly as a mold for producing the appliance.
- the prototyping machine 201 receives the individual digital data sets and produces one structure corresponding to each of the desired appliances.
- the rapid prototyping machine 201 may utilize a resin having non-optimum mechanical properties and which may not be generally acceptable for patient use, the prototyping machine typically is used to produce molds which are, in effect, positive tooth models of each successive stage of the treatment.
- a conventional pressure or vacuum molding machine is used to produce the appliances from a more suitable material, such as 0.03 inch thermal forming dental material, available from Tru-Tain Plastics, Rochester, Minn. 55902.
- Suitable pressure molding equipment is available under the trade name BIOSTAR from Great Lakes Orthodontics, Ltd., Tonawanda, N.Y. 14150.
- the molding machine 251 produces each of the appliances directly from the positive tooth model and the desired material.
- Suitable vacuum molding machines are available from Raintree Essix, Inc.
- the appliances can be supplied to the treating professional all at one time.
- the appliances are marked in some manner, typically by sequential numbering directly on the appliances or on tags, pouches, or other items which are affixed to or which enclose each appliance, to indicate their order of use.
- written instructions may accompany the system which set forth that the patient is to wear the individual appliances in the order marked on the appliances or elsewhere in the packaging. Use of the appliances in such a manner will reposition the patient's teeth progressively toward the final tooth arrangement.
- the treating clinician may wish to evaluate the patient's progress during the course of treatment.
- the system can also do this automatically, starting from the newly-measured in-course dentition. If the patient's teeth do not progress as planned, the clinician can revise the treatment plan as necessary to bring the patient's treatment back on course or to design an alternative treatment plan.
- the clinician may provide comments, oral or written, for use in revising the treatment plan.
- the clinician also can form another set of plaster castings of the patient's teeth for digital imaging and manipulation. The clinician may wish to limit initial aligner production to only a few aligners, delaying production on subsequent aligners until the patient's progress has been evaluated.
- FIG. 9 is a simplified block diagram of a data processing system 311 that may be used to develop orthodontic treatment plans.
- the data processing system 311 typically includes at least one processor 303 which communicates with a number of peripheral devices via bus subsystem 305 .
- peripheral devices typically include a storage subsystem 307 (memory subsystem 311 and file storage subsystem 314 ), a set of user interface input and output devices 318 , and an interface to outside networks 316 , including the public switched telephone network.
- This interface is shown schematically as “Modems and Network Interface” block 316 , and is coupled to corresponding interface devices in other data processing systems via communication network interface 324 .
- Data processing system 311 could be a terminal or a low-end personal computer or a high-end personal computer, workstation or mainframe.
- the user interface input devices typically include a keyboard and may further include a pointing device and a scanner.
- the pointing device may be an indirect pointing device such as a mouse, trackball, touchpad, or graphics tablet, or a direct pointing device such as a touchscreen incorporated into the display, or a three dimensional pointing device, such as the gyroscopic pointing device described in U.S. Pat. No. 5,440,326, other types of user interface input devices, such as voice recognition systems, can also be used.
- User interface output devices typically include a printer and a display subsystem, which includes a display controller and a display device coupled to the controller.
- the display device may be a cathode ray tube (CRT), a flat-panel device such as a liquid crystal display (LCD), or a projection device.
- the display subsystem may also provide non-visual display such as audio output.
- Storage subsystem 307 maintains the basic required programming and data constructs. The program modules discussed above are typically stored in storage subsystem 307 . Storage subsystem 307 typically comprises memory subsystem 309 and file storage subsystem 314 .
- Memory subsystem 309 typically includes a number of memories including a main random access memory (RAM) 310 for storage of instructions and data during program execution and a read only memory (ROM) 312 in which fixed instructions are stored.
- RAM main random access memory
- ROM read only memory
- the ROM would include portions of the operating system; in the case of IBM-compatible personal computers, this would include the BIOS (basic input/output system).
- File storage subsystem 314 provides persistent (non-volatile) storage for program and data files, and typically includes at least one hard disk drive and at least one floppy disk drive (with associated removable media). There may also be other devices such as a CD-ROM drive and optical drives (all with their associated removable media). Additionally, the system may include drives of the type with removable media cartridges.
- the removable media cartridges may, for example be hard disk cartridges, such as those marketed by Syquest and others, and flexible disk cartridges, such as those marketed by Iomega.
- One or more of the drives may be located at a remote location, such as in a server on a local area network or at a site on the Internet's World Wide Web.
- bus subsystem is used generically so as to include any mechanism for letting the various components and subsystems communicate with each other as intended.
- the other components need not be at the same physical location.
- portions of the file storage system could be connected via various local-area or wide-area network media, including telephone lines.
- the input devices and display need not be at the same location as the processor, although it is anticipated that personal computers and workstations typically will be used.
- Bus subsystem 305 is shown schematically as a single bus, but a typical system has a number of buses such as a local bus and one or more expansion buses (e.g., ADB, SCSI, ISA, EISA, MCA, NuBus, or PCI), as well as serial and parallel ports. Network connections are usually established through a device such as a network adapter on one of these expansion buses or a modem on a serial port.
- the client computer may be a desktop system or a portable system.
- Scanner 320 is responsible for scanning casts of the patient's teeth obtained either from the patient or from an orthodontist and providing the scanned digital data set information to data processing system 311 for further processing.
- scanner 320 may be located at a remote location and communicate scanned digital data set information to data processing system 311 via network interface 324 .
- Fabrication machine 322 fabricates dental appliances based on intermediate and final data set information received from data processing system 311 .
- fabrication machine 322 may be located at a remote location and receive data set information from data processing system 300 via network interface 324 .
- the invention has been described in terms of particular embodiments. Other embodiments are within the scope of the following claims.
- the three-dimensional scanning techniques described above may be used to analyze material characteristics, such as shrinkage and expansion, of the materials that form the tooth castings and the aligners.
- the 3D tooth models and the graphical interface described above may be used to assist clinicians that treat patients with conventional braces or other conventional orthodontic appliances, in which case the constraints applied to tooth movement would be modified accordingly.
- the tooth models may be posted on a hypertext transfer protocol (http) web site for limited access by the corresponding patients and treating clinicians.
